What are the future plans for validation with GridView? Do you plan to support multiple levels of validation, such as errors/warnings/information? I have a situation where my customers want to be warned of a value differential, but still want to be able to save their data.

Hello David,
We don't have such plans. However you can use Row/CellTemplateSelector and Row/CellStyleSelector properties to achieve this via a proper view model. For more information about selector properties you can take a look at this blog post.

I don't see the CellTemplateSelector as available. When will the service pack including this be available?

Ok, I've got a copy that has CellSytleSelector. How do I get the object that is bound to DataMemberBinding? The item that is passed to the style selector is the item bound to the row, not the cell. I need the object bound to the cell.

Hello,
The second argument is the cell itself.

Unfortunately using a selector seems to be insufficient. It only fires when a cell comes into view. I would need it to fire anytime the cell had been edited or anytime a notifyonvalidation occured.

Hi David Brenchley,

Indeed validation notifications provided by INotifyDataErrorInfo and (IDataErrorInfo + INotifyPropertyChanged) interfaces affects only visible items, because visual objects for items and cells are created only for visible ones.
You could use RowTemplate/StyleSelector which could be bound to a property which indicates that there is an error for this item, but again this will work only for visible items. You could by-pass this behavior if you turn off row and column virtualization. This is not recommended (but it is an option if you don't have large data with too much columns).
